Paste style wrote the copied fields straight onto the element, although a pasted look is meant to be the style operation the assistant sends. It now runs the engine's own restyle (bookElementStyled): a colour or face pasted by hand takes the element off the theme, so the next theme applied no longer brings the old colour back; a plain fill replaces the paint of the shape it lands on instead of staying hidden under it; and a line takes another line's look without its points, which are its course, not its look. A background picked by hand in the inspector kept the page's link to the theme, so the next theme applied set the page back to the theme's colour. The picker and the background operation now paint through one helper that takes the link away (withSpreadPaintByHand). Giving one page's background to every page carries that page's link along, or takes the others' away when it was painted by hand. A built-in layout, a book's own layout and laying a page out again from its entry ignored locks in the Studio: a locked shape was dropped and a locked photo poured into a slot unlocked, while the assistant's layout operation left both where they were. All four now lay a page out around its locked elements through one function (layoutAroundLocks), which the engine's layout operation uses too. Fill page and fill spread kept the photo in its group, so the background picture was selected and dragged with its caption and listed under the group at the front. It leaves its group as the engine's fill does, and a group left with one member goes.
@trek/shared
Single source of truth for TREK's API contracts, expressed as Zod schemas and consumed by both the server (request validation + inferred DTO types) and the client (typed requests/responses).
This package is part of the incremental NestJS + React 19 migration (see the "Brownfield Rewrite" board). It is intentionally dormant until modules start importing it — adding it changes nothing for users.
Rules
- One folder per domain:
src/<domain>/<domain>.schema.ts(+.spec.ts). - Domain-agnostic building blocks live in
src/common/. - A route is only considered migrated once its contract lives here.
- Schemas are the source of truth; server DTOs and client types are inferred from them
(
z.infer<typeof schema>), never hand-duplicated.
Consumption (dev)
Both apps resolve @trek/shared to this package's TypeScript source:
- Server (
tsx): viapathsinserver/tsconfig.json. - Client (
vite): viaresolve.aliasinclient/vite.config.ts(+pathsfor the type-checker).
Production packaging (Docker / workspace wiring) is introduced in card F2, when the server first depends on this package at runtime. Until then prod builds are untouched.
Not yet here
The canonical error envelope is finalised in card F5 (it must match TREK's current Express error responses byte-for-byte), so it is deliberately not invented in F1.
